<p>MemoryLifter uses virtual flashcards and the Leitner box system to augment 
 your learning ability.</p>

<p>&nbsp;</p>

<p class=SubTopic1><b style="font-weight: bold;">The box system</b></p>

<p>The box system (also called &quot;Leitner system&quot;) was originally 
 conceived by German learning-psychologist Sebastian Leitner in the 1970s. 
 </p>

<p>Its purpose is to provide a structure to help people learn and retain 
 information in short-term and long-term memory.</p>

<p>&nbsp;</p>

<p>In the box system flashcards are assigned to a set of <i>x</i> boxes 
 (10 boxes in the case of MemoryLifter).</p>

<p>Box sizes increase with the box's number. </p>

<p>By the time a card has been promoted to the highest box, the material 
 should be fixed in long-term memory.</p>

<p>&nbsp;</p>

<p>The quantity of flashcards inside each box level provides a quick feedback 
 of the current state of the user's knowledge and memory retention (short-term 
 and/or long-term).</p>

<p>&nbsp;</p>

<p class=SubTopic1><b style="font-weight: bold;">MemoryLifter's box system 
 algorithm</b></p>

<p>MemoryLifter uses a slightly modified version of the original box system 
 algorithm to present and track the cards for learning.</p>

<p>&nbsp;</p>

<ol style="list-style: decimal;"

	<li class=kadov-p-CNumList><p class=NumList>Initially, all cards are 
 pulled from the pool, which contains all available cards.</p></li>
	
	<li class=kadov-p-CNumList><p class=NumList>MemoryLifter checks whether 
 any of the boxes are full. <br>
	If so, it asks a card from that box. <br>
	If none of the boxes are full, MemoryLifter places a new card from 
 the pool in the first box and asks it.</p></li>
	
	<li class=kadov-p-CNumList><p class=NumList>If a card is answered correctly, 
 MemoryLifter promotes it to the next box.<br>
	Otherwise, it is demoted to box 1.</p></li>
	
	<li class=kadov-p-CNumList><p class=NumList>When placing a card in 
 a box, MemoryLifter puts it at the end of the box. <br>
	When asking cards from the box, they are asked in the order they were 
 placed in the box (first in - first out principle).</p></li>
	
	<li class=kadov-p-CNumList><p class=NumList>MemoryLifter continues 
 with step 2 to 4 until the pool is empty.</p></li>
	
	<li class=kadov-p-CNumList><p class=NumList>If the pool is empty, the 
 oldest card from the Learning Module will be asked. <br>
	A message box will be opened to inform you of this.</p></li>
